Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current animal sensory discrimination apparatuses are limited in their ability to rapidly test multiple samples and provide direct measures of sensory perception, often experiencing clogging issues and restricting the number and rate of solutions that can be sampled.
Innovation Solution
A high-throughput apparatus with a self-contained, low-contamination environment that allows rapid sampling of multiple sensory samples using a support platform, signaling means, and response obtaining mechanisms, enabling direct measurement of sensory perception through a modular operant panel with levers and nose poke wells, and sample plate with multiple wells for efficient sampling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a limited number of reservoirs connected through tubing to a manifold are used for sample delivery, then the apparatus structure is simple, but the number of solutions that can be sampled and the testing rate are limited
Solution Approach 1:
The apparatus divides the sample delivery system into multiple independent reservoirs (e.g., 96-well plates with individual wells) rather than using a single centralized reservoir system. Each well can be independently accessed, allowing simultaneous or sequential testing of numerous samples without requiring complex interconnecting tubing and manifolds. This segmentation enables high-throughput sampling while maintaining relative structural simplicity.
2Reliability
If gravity-controlled sample flow is used, then the sample delivery mechanism is simple, but clogging of tubing occurs and sample delivery is compromised
Solution Approach 1:
The system employs automated sample delivery mechanisms (such as robotic arms, automated pipettes, or computer-controlled dispensing systems) that can precisely position and deliver samples without manual intervention. These self-service mechanisms reduce the risk of clogging by maintaining consistent flow rates and proper sample handling, while also eliminating the need for complex gravity-dependent tubing arrangements. The automation ensures reliable sample delivery through programmed sequences and error detection.
3Measurement precision
If a lickometer approach is used for taste measurement, then the throughput is higher, but only an indication of avoidance or preference is provided without direct sensory perception measurement
Solution Approach 1:
The apparatus introduces an intermediary measurement system between the animal and the sample that captures direct sensory responses. This includes using automated lick detection sensors, nose-poke wells with photodetectors, or other intermediary devices that translate animal behavior into quantifiable data. These intermediaries enable precise measurement of sensory perception (such as lick frequency, duration, and pattern) while maintaining high throughput through automated data collection and analysis, avoiding the need for manual observation.
